If x= 5 and y = 2, work out the value of a) 3x + y
b) 2x2
c) (x - y)2
Answer:
17, 50, 9
Step-by-step explanation:
Hello
We already know the values of x and y, 5 and 2.
All we have to do to figure out a, b, and c, is to plug in those known values.
a) 3x + y
Let's plug in x and y as 5 and 2
3(5) + 2
15 + 2
17
b) 2x^2
2(5)^2
2(25)
50
c) (x - y)^2
(5 - 2)^2
3^2
9
Answer:
A) 3(5)+2= 17
B) 2(5)2= 50
C) (5-2)2= 9

Help please :( I am stuck
Answer: We all hate it when we are stuck! The slope is -1/2.
Step-by-step explanation: To find the slope, figure out the change of x divided by the change of y. The change of y is -1, and the change of x is 2. Therefore, the slope of the line is -1/2.
Select the expression equivalent to 4(– 7) + 8.
Answer:
-20
Step-by-step explanation:
According to order of operations, multiplication comes before addition.
4(– 7) + 8 =
-28 + 8 =
-20
An expression equivalent to 4(– 7) + 8 would be:
8 + 4(-7)
This is true because of the commutative property which states that a+b=b+a
Answer:
-20
Step-by-step explanation:
It is very simple!
4x-7= -28
-28+8=20

Answer: Create equations. Top length=Bottom length
Left side = right side.
Combine like terms and rewrite the equations.
Use the new equations to create a system of equations to solve for x and y.
Once you have x and y, you can substitute those in the expressions for the lengths of the parallelogram.
You should end up with top and bottom lengths of 10. The sides are 9.
Step-by-step explanation:
3x-5 = 18 -2y . Rewrite as 3x + 2y = 23
x+4 = 21 -3y Rewrite as x + 3y = 17
The system of equations is
3x + 2y = 23 and x + 3y = 17 . To solve by substitution, multiply the second equation by -3 It becomes -3x-9y= -51 Add the equations so the x terms cancel. Solve for y
3x + 2y = 23
-3x - 9y = -51
0 -7y = - 28 Divide both sides by -7. y = 4
Substitute 4 for y, solve for x
x + 3(4) = 17
x + 12 = 17 . Subtract 12 from both sides x = 5
Substitute the values of x and y in the expressions
Top: 3x-5 is 3(5) -5 becomes 10
Bottom: 18 -2y is 18 - 2(4) becomes 10
Left: x +4 is (5) + 4 becomes 9
Right: 21 - 3y is 12 -3(4) becomes 9

John rode 2 kilometers on his bike. His sister Sally rode 6,000 meters on her bike. How many more kilometers did Sally ride?
Answer:
I don't understand, please write again
Answer:
Sally rode 4 kilometers more than her brother.
Step-by-step explanation:
1,000 meters = 1 kilometer
So if you convert Sally's meters into kilometers, you get 6 kilometers. John rode 2 kilometers so you do 6 kilometers - 2 kilometers = 4 kilometers.
Now you got your answer!
Hope this helped.
Choose the linear inequality that describes the graph. The gray area represents the shaded region.
4x – 6y ≥ 10
4x + 6y ≤ 10
4x + 6y ≥ –10
4x + 6y ≥ 10
please help !
Answer:
4x+6y<=10
Step-by-step explanation:
The linear inequality that describes the graph is 4x+ 6y ≤ 10.
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
As, The bold straight line passes through the points (1,1) and (-2, 3).
so, equation of line will be
(y- 1) = (3-1)/ (-2-1) (x-1)
y-1 = 2 / (-3) (x-1)
-3y + 3 = 2x - 2
-3y -2x = -5
If we multiply by 2 both side we get
-6y - 4x = -10
4x+ 6y= 10
So, the required inequality for gray area is 4x+ 6y ≤ 10.

The angle of elevation from a boat to the top of a lighthouse is 50°.
If the boat is 150 feet from the base of the lighthouse, how tall is the lighthouse?
Round answer to the nearest foot.
9514 1404 393
Answer:
179 ft
Step-by-step explanation:
The applicable trig relation is ...
Tan = Opposite/Adjacent.
The height of the lighthouse is the opposite side of the right triangle. The adjacent side to the angle of elevation from the boat is the distance to the lighthouse base. Then ...
tan(50°) = height/(150 ft)
height = (150 ft)(tan(50°)) ≈ 178.76 ft
The height of the lighthouse is about 179 feet.
